And why are they built that way? Because the racers are not smart enough to realize, they constantly want some new rule, that obsolete what they have now. And want to throw more money after some new trick part that cost more. And that widens the gap between the have and have not's. A good example of good rules is look at the stock car class that runs area dirt tracks. They have had the same set of rules for 20 years. And do not think, I am comparing the two just saying if all the new trick item were banned and the rules were stable it might keep the racer from spending them selves out of racing.

It is like the people who race asphalt do not like competition, and try to out spend everyone to have them to quit or go else where. So they can say the won the feature but forget to say the class had 10 cars.
